These ARF balsa kits are really a pleasure to assemble and fly. Each of these model almost pop itself together and can be built, adjusted, charged and ready for flights in one evening. Complete linkage hardware is included in every kit, and time-conscious modelers will appreciate the fact that the holes for the control horns come factory drilled in the control surfaces. For intermediate to advanced pilots. To complete these kits, you will need the following electronics:  Standard Servos, Outrunner Brushless Motors, Brushless ESC Speed Controllers, Li-Polymer Batteries, Transmitters and Receivers.
